Öğe A 37-Year-Old Asymptomatic Male Case of Mass Lesion in the Right Upper Zone detected on Chest x-Ray: What is your Diagnosis?(Aves, 2015) Alaşan,Fatih; Ünlü, Elif Nisa; Annakkaya, Ali Nihat…Öğe Akut el bileği ağrısının nadir bir nedeni: Persistan median arter trombozu(2016) Ünlü, Elif Nisa; Soyupek, Feray; Yılmaz, Ömer; Aktaş, Aykut Recep; Koç, Ural; Büyükkaya, RamazanPersistan median arter (PMA), elin vasküler yapısının anatomik bir varyasyonudur ve genellikle asemptomatiktir. Persistan median arterin varlığı ve trombozu, başta karpal tünel sendromu olmak üzere çeşitli komplikasyonlara yol açabilmektedir. Akut PMA trombozunun erken tanı ve tedavisi önemlidir; zira erken antikoagülan tedavi ile birçok komplikasyon ve cerrahi gereksinimi önlenebilmektedir. Bu yazıda, 36 yaşında bir kadın olguda akut el bileği ağrısına neden olan tromboze PMA'nın görüntüleme bulguları sunuldu. Erken antikoagülan tedavi, semptomların tamamen iyileşmesini sağladı. Hastada karpal tünel sendromu veya başka bir bulgusu yoktuÖğe Assessment of anterior subcutaneous hypersignal on proton-density-weighted MR imaging of the knee and relationship with anterior knee pain(Elsevier Masson, Corporation Office, 2017) Ünlü, Elif Nisa; Turhan, Yalçın; Köş, Durdu Mehmet; Şafak, Alp AlperPurpose: The purpose of this study was to evaluate the prevalence of anterior subcutaneous hypersignal indicating edema on proton-density (PD)-weighted MRI of the knee and to determine whether reporting anterior edema is clinically relevant. Materials and methods: One hundred and ninety-one knee MRIs from 162 patients were reviewed for anterior subcutaneous edema. There were 92 men and 70 women with a mean age of 41.72 years +/- 13.92 (SD) (range, 15-80 years) years and a mean body weight of 75.94 kg +/- 12.54 (SD) (range, 50-130 kg). The MRI findings were compared with patient age, gender, body weight, history of repetitive microtrauma and clinical findings. Patellar and trochlear chondropathy, medial plica, joint effusion, synovitis, infrapatellar fat-pad signal intensity, suprapatellar fat-pad signal intensity with mass effect, quadriceps and patellar tendon abnormalities were also reviewed. Results: An anterior hypersignal on PD-weighted MRI was detected in 158/191 MR examinations (82.7%) and 104 (84.6%) of these cases had histories of anterior knee pain. No correlation between anterior pain and anterior edema was found (P = 0.42). Age (P < 0.0001), weight (P < 0.0001), and repetitive microtrauma (P = 0.001) were identified as significant variables associated with anterior edema. Conclusion: Anterior edema may be a physiological phenomenon or degenerative change related to patient age, weight, and knee movement or mechanics. It should not be reported as apathological finding on MRI unless clinical findings support regional infection or inflammation. (C) 2016 Editions francaises de radiologie.

Magnetic resonance (MR) imaging is a commonly used diagnostic method in the preoperative diagnosis of these tumors. In this study, we demonstrated an isthmus between the right and left carotid body tumors in a patient with bilateral CBT. The left CBT also was associated with a saccular aneurysm of left external jugular vein.Öğe Bilateral dacryoadenitis associated with IgG4-related disease presenting as orbital pseudo-inflammatory tumor(Elsevier France-Editions Scientifiques Medicales Elsevier, 2022) Oğul, Hayri; Ünlü, Elif Nisa[Bastract Not Available]Öğe Bronchiolectasis due to giant thoracic vertebral osteophytes(Elsevier Science Inc, 2015) Ünlü, Elif Nisa; Büyükkaya, Ayla; Balbay, Ege Güleç…Öğe A case of thoracoabdominal localized Mondor's disease in a young man [Genç erkekte torakoabdominal yerlesimli mondor hastali?i](Turkiye Klinikleri, 2014) Güleç, Ali İhsan; Yavuzcan, Gizem; Uslu, Esma; Başkan, Elife; Ünlü, Elif NisaMondor's disease is a special form of superficial thrombophlebitis of subcutaneous veins. It is more common in women. Penile Mondor's disease is generally detected in male patients. We reported a 30-year-old male patient having right thoracoabdominal wall Mondor's disease. The patient did not have any history of trauma, infection, physical activity and previous surgery. A linear, cord-like fibrous nodule with skin color was identified on the right thoracoabdominal wall in a diameter of 0.5 cm and length of 10 cm was detected in physical examination. The patient was given non-steroidal anti-inflammatory drug treatment. Mondor's disease should be kept in mind in the differential diagnosis of painful palpable cord-like lesions at thoracoabdominal wall in the presence of subcutaneous infiltration without any predisposing factors in healthy males.

The lesion is most commonly seen in people in the third and fourth decade. There are three variants of ossifying fibroma; juvenile trabecular ossifying fibroma, juvenile psammomatoid ossifying fibroma, and COF. COF is highly cellular and contains a fibrous tissue that has different amounts of calcified tissue. Although histologically benign, it has a significant growth potential.Öğe Cerebellar Developmental Venous Anomaly Causing Tinnitus and Hemifacial Spasm: A Case Report(Sage Publications Inc, 2022) Oğul, Hayri; Ünlü, Elif Nisa; Güçlü, Derya; Köksal, Ali[Bastract Not Available]Öğe Clinical importance of preoperative fine needle aspiration biopsy and computed tomography in parotid gland masses(2016) Şahin, Ender; Ünlü, İlhan; Ünlü, Elif Nisa; Kaptan, Zeynep; Uzunkulaoğlu, Hakkı; Samim, Ethem Erdal; Karadavut, YunusObjectives. To determine the diagnostic value of fine needle aspiration biopsy (FNAB) and computedtomography (CT) in parotid masses in the basis of postoperative histopathological results. Methods. The recordsof 68 patients diagnosed with a parotid mass and undergone parotis surgery between November 2004 andFebruary 2011 were evaluated retrospectively. Preoperative FNAB and the CT findings were compared withpostoperative histopathological findings. Results. The study included 36 (58%) female and 26 (42%) malepatients. The mean age of the patients was 43.9 years. No statistically significant difference was detected withregards to the performances of both FNAB and the CT (p0.797). When it was evaluated in a detail, theperformance of parotid CT(81.82%) to diagnose a mass in parotid gland was relatively better than FNAB(72.73%). The performance of FNAB (94.12%) to detect healthy ones was also greater than parotid CT (90.2%).Conclusion. We emphasize that preoperative FNAB and parotid CT should be performed to the patients witha parotid mass. The use of these two tests together can minimize the risk rate have been proved.Öğe CT versus grayscale rib series for the detection of rib fracture(W B Saunders Co-Elsevier Inc, 2015) Güneş, Harun; Ünlü, Elif Nisa; Sarıtaş, Ayhan…Öğe Elongation and aberrant articulation of cervical transverse processes mimicking osteochondroma(Elsevier Science Inc, 2015) Ünlü, Elif Nisa; Büyükkaya, Ayla; Ünlü, İlhan; Boran, Mertay; Güneş, Harun…Öğe Evaluation of middle ear pressure in the early period after adenoidectomy in children with adenoid hypertrophy without otitis media with effusion(W B Saunders Co-Elsevier Inc, 2015) Ünlü, İlhan; Ünlü, Elif Nisa; Kesici, Gülin Gökçen; Güçlü, Ender; Yaman, Hüseyin; İlhan, Ethem; Memiş, MehmetObjective: Our aim was to analyze the changes in middle ear pressure in the early period after adenoidectomy in children with adenoid hypertrophy without otitis media with effusion. Methods: This prospective, descriptive study was performed on 64 patients (with normal tympanic membranes and tympanograms) undergoing adenoidectomy or adenotonsillectomy. All patients were operated by single experienced team using curettage technique. First tympanometry was done on the day before surgery. Tympanometry was repeated on the first-, third-, and seventh-day after the operation. Patients are separated into two groups according to age as patients younger than 6 years (Group A) and patients older than 6 years (Group B). All data were separately evaluated for each ear using Jerger Classification. Results: Of the 64 patients included in the study, 35 were male and 29 were female, and the average age was 91.01 +/- 37.4 (35-178) months. Pathological decreases in the middle ear pressures of at least one ear were determined in 48 (75%) patients on the first postoperative day and in 10 (15.6%) patients on the third postoperative day. Middle ear pressures returned to preoperative values by the seventh postoperative day except in two patients. There were statistically significant differences (p <0.0001) among preoperative and first, third, and seventh postoperative day mean middle ear pressure. There were no statistically significant differences between Groups A and B in terms of tympanometry values of both ears obtained preoperatively and on the first, third, and seventh postoperative day. Conclusion: In our study, temporary eustachian dysfunction and aural fullness occur in the early period after adenoidectomy and/or adenotonsillectomy. This situation may be due to post-surgery clots and edema in nasopharynx. We consider that tubal orifice can be exposed to surgical trauma as adenoidectomy surgeries are done by curettage technique. There is a need for comparative studies using microdebrider or laser adenoidectomy accompanied by an endoscope. (C) 2015 Elsevier Inc.

They are divided into three groups as ivory, mature, and mixed form. We reported demonstrative radiological features of an unusual case of giant osteoma presenting with proptosis and diplopia.Öğe An interesting combination of anterior and posterior arch defects of atlas(Elsevier Science Inc, 2016) Ünlü, Elif Nisa; Aydın, Leyla Yılmaz; Ünlü, İlhan; Sönmez, Feruza Turan…Öğe Is There a Relationship Between Paratracheal Air Cysts and Upper Lobe Fibrosis?(Lippincott Williams & Wilkins, 2016) Ünlü, Elif Nisa; Balbay, Ege Güleç; Boran, Mertay; Sungur, Mehmet Ali; Büyükkaya, Ayla; Şafak, Alp AlperObjective The purpose of this study was to determine the characteristics of paratracheal air cysts (PACs) and their relationship with upper lobe pulmonary fibrosis. Materials and Methods The routine thoracic computed tomography scans of 3549 patients carried out between January 2014 and April 2015 were retrospectively evaluated. The presence, location, structural characteristics (uniloculated or multiloculated), number of cysts, and anterior-posterior and transverse dimensions of the PAC and its communication with the tracheal lumen were evaluated. The presence of upper lobe fibrosis, emphysema, and bronchiectasis was also evaluated. The relationship between upper lobe fibrosis, emphysema, bronchiectasis, and the presence of paratracheal cysts was evaluated in all patients. An equal number of randomized patients with no paratracheal cysts were selected as a control group. Results A total of 190 PAC cases were diagnosed, with a prevalence rate of 5.35%: 146 (76.8%) of the cases were men, 44 (23.2%) were female, and the mean (SD) age was 53.79 (16.64) years (range, 12-89 years). The control group included 105 men (57.4%) and 78 women (42.6%), and the mean (SD) age was 53.87 (16.65) years (range, 13-87 years). The groups were similar in terms of age (P = 0.876), whereas the proportion of men in the PAC group was significantly higher (P < 0.001). Most of the PACs were located on the right side (n = 188, 98.9%). The incidence of fibrosis in the paratracheal cyst group was 45.8% (n = 87) compared with 19.5% (n = 37) in the control group; this difference was statistically significant (P < 0.001). The prevalence rates of emphysema in the cyst group and the control group were 29.5% (n = 56) and 11.6% (n = 22), respectively, and the difference was statistically significant (P < 0.001). When the groups were compared regarding bronchiectasis (scar and non-scar related), the rate of bronchiectasis in the paratracheal cyst group was 17.9% (n = 34), compared with 3.7% (n = 7) in the control group; this difference was statistically significant (P < 0.001). Conclusions Paratracheal air cysts are relatively common, but the etiology is still unclear. We detected increased rates of cyst formation that may result from the traction effect on the tracheal wall in the presence of upper lobe fibrosis.Öğe Median nerve entrapment due to accessory palmaris longus muscle: MRI and sonography findings(BMJ Publishing Group, 2018) Güçlü, Derya; Arıcan, Mehmet; Ünlü, Elif Nisa[No abstract available]Öğe Membranous Nasopharyngeal Stenosis: Case Report(Sage Publications Inc, 2022) Güçlü, Derya; Ünlü, Elif Nisa; Oğul, HayriNasopharyngeal stenosis is a rare condition and occurs usually secondary to nasopharyngeal or oropharyngeal surgery and radiotherapy. It may cause obstructive symptoms in patients and is diagnosed usually with nasopharyngoscopy. Treatment is difficult and requires different surgical techniques including balloon dilatation. Even after a successful surgery, recurrence is very common.
